FCM for proliferating Tregs induced by CD28SA. a Three-color FCM analysis of the splenic lymphocytes for lymphocyte markers, Treg transcription factor (Foxp3), and EdU at day 3 after CD28SA injection (0.5 mg/rat). b Dose response of Foxp3+Tregs with different markers to CD28SA. Absolute number of EdU+ proliferating Tregs with different lymphocyte markers/spleen, showing 0.5–1.0 mg induces an intense response

Mouse anti Rat CD4 (Domain 1) antibody, clone OX-38 (MCA372G) used for the identification of CD4 expressing cells in rat spleen by flow cytometry and immunofluorescence.
Image caption:
Assessment of proliferating lymphocytes in the spleen activated by CD28SA. a FCM analysis of the splenic lymphocytes for lymphocyte markers and EdU at day 3 after CD28SA injection (0.5 mg/rat). Note increase in TCRαβ+, CD4+, or CD25+ EdU+ cells but not CD8β+EdU+ cells compared to control. b Dose response of splenic lymphocytes to CD28SA. Absolute number of EdU+ proliferating cells with different lymphocyte markers/spleen, showing 1.0 mg group induces the highest response. c Triple immunofluorescent staining for lymphocyte markers (indirect staining with Alexa-680-conjugated anti-mouse IgG, green), EdU (Alexa-594-conjugated azide, red) and type IV collagen (indirect staining with AMCA-conjugated anti-rabbit IgG, white). Day 3 after CD28SA injection (0.5 mg/rat). Pseudocolors were assigned using AxioVision software. Scale bar 100 μm. The splenic PALS area with the central arteries is depicted by type IV collagen. Proliferating cells with different markers are shown as green cells with red nuclei (inset of lower panel).

| Mouse anti Rat CD4 (Domain 1) antibody, clone OX-38 recognizes the rat CD4 cell surface antigen, also known as W3/25 antigen or T-cell surface antigen T4/Leu-3. CD4 is a 430 amino acid ~55 kDa single pass type I transmembrane glycoprotein expressed by T helper cells, monocytes and macrophages. Clone OX-38 competes for binding with Mouse anti Rat CD4 antibody, clone W3/25 (MCA55R). Mouse anti Rat CD4 (Domain 1) antibody, clone OX-38 has been utilized successfully for the in vitro depletion of T helper cells (Pusic et al. 2015). |
